Keith Company, Brockton, Mass., a corporation of Massachusetts Application November 2, 1953, Serial No. 389,637 1 Claim. (CI. 3616) This invention relates to a new and improved shoe construction.

One advantage of my new construction is its sturdiness and resistance to wear and tear.

Another advantage is that in my new shoe the cleancut form of only a single row of stitching through the upper is achieved, even though a welt is not used.

Still another advantage of my new construction is that upper, innersole, and outersole are solidly joined in a unitary structure by a single row of stitching.

Generally speaking, my invention provides for an improved construction in which the lining of an upper, enclosing shank and forepart of a shoe, is stitched down to an innersole therearound and the upper is then formed to follow the contours of the lining over the vamp and stitches and then led around the peripheral rim of the innersole and secured therebeneath, a lower sole (which may suitably be the outersole) being placed beneath the whole and the upper, innersole and lower sole being joined into a unitary structure by stitches passing therethrough.

Other objects, features, and advantages of my invention will be apparent from the drawings and following description of a preferred embodiment thereof in which:

Fig. 1 is a side elevation of a shoe made in accordance with the invention;

Fig. 2 is a cross-sectional view on line 22 of Fig. l of a portion of the shoe; and

Fig. 2a is a cross-sectional view similar to Fig. 2 and showing a portion thereof on an enlarged scale illustrating the layers of cement which assist in joining the several parts to each other; and

Fig. 3 illustrates the first stage in making my new shoe, showing an upper and lining for the forepart and shank of a shoe tacked down to a last; and

Fig. 4 illustrates three following stages in making the shoe, by means of sections along line 4--4 of Fig. 3.

Referring now to the drawings, there is shown in Figs. 1 and 2 a preferred embodiment of my novel shoe construction.

A lining 2 is stitched down to an innersole 4 around the forepart and shank of said shoe, the resulting line of stitches 6 being substantially parallel with the peripheral edge 8 of said innersole, and set back a substantial distance therefrom. The lining 2 is cemented to the top 10 of the innersole 4 between said stitches and said edge 8, and bends down along said edge and is cemented thereto.

The upper 14 is cemented to the lining 2 over the entire surface of the latter so as to make it follow substantially the conformation thereof, and also to cover the upper surface of the stitches 6. A fabric piece 16 may suitably be used between the lining 2 and upper 14 to facilitate said cementing and give added strength. The upper 14 is carried beyond the bottom of the innersole peripheral edge 8, being cemented to the bottom 18 thereof over an area extending inwardly from said edge for a substantial distance. The edge 8, top 10, and portion of bottom 18 below top 10 define what may be spoken of as the peripheral rim 12 of the innersole.

The cement layer between the lining 2 and the fabric 16 is indicated by the numeral 19; that between the fabric 16 and the upper 14 by the numeral 21; that between the top surface of the inner sole 4 and the lining 2 by the numeral 23; that between the bottom of the inner sole 4 and the folded-under portion of the upper 14 by the numeral 25; and that between the top of the outer sole 20 and the folded-under portion of the upper 14 by the numeral 27.

The outersole 20 is joined to the upper 14, lining 2, and innersole 4 by a row of stitches 22 extending vertically through all four said elements and following a line sub stantially parallel to the peripheral edge 24 of said outersole. A layer of cork filler 26 may suitably be interposed between the innersole 4 and outersole 20.

A rubber soled shoe according to my invention may suitably be made by substituting as the lower sole instead of outersole 20 a so-called doubler sole, and attaching thereto a rubber outersole by means familiar in the art.

Referring now to Figs. 3 and 4, which taken with Fig. 2 illustrate a preferred way of making my new shoe, there is shown in Fig. 3 and in Fig. 4a an innersole 4 tacked to a last 30 and having a lining 2 lasted to said innersole around the forepart and shank thereof. Said lining may suitably be stitched down to said innersole by means of a stitchdown thread lasting machine, United Shoe Machinery Corporation Model B. This operation may suitably be performed after the cloth 16 and upper 14 are partially formed over and cemented in place on said lining, but with said upper extending freely so as not to be penetrated by the stitches of said lasting operation.

The lining 2 is next cemented to the top 10 and edge 8 of the innersole peripheral rim 12, and trimmed off along the bottom of said edge, as shown in Fig. 4b.

Thereafter, as shown in Fig. 4c, the upper 14 is formed over and cemented in place to the remainder of the lining 2, in such a manner as to follow its conformations closely down along the top 10 and edge 12 of the peripheral rim 8. Said upper is additionally bent over along the bottom surface 18 of the innersole 4 and cemented thereto, after removing tacks. Said bottom surface may then suitably be filled in, especially centrally thereof, with a filling layer 26 of material such as cork.

In the final stage, as shown in Fig. 2, the upper 14, lining 2, innersole 4 and outersole 20 are then joined by a row of stitches 22, preferably lock stitches, extending vertically therethrough. Such stitching may suitably be performed using a Goodyear Outsole Rapid Lockstitch machine such as United Shoe Machinery Corporation Model A.

It will be apparent that other embodiments of my invention may be made by those skilled in the art without departing from the spirit of my invention.

I claim:

In a shoe, the combination of an outersole, an innersole, an upper enclosing the forepart and shank of said shoe, and a lining for said upper, said lining being attached down to said innersole by stitching along a line set back from the periphery thereof and cemented to the rim of said periphery along the top and edge thereof, said outersole being positioned beneath said innersole, and said upper being cementedly joined to and following closely said lining outside thereof, over said stitching, in a substantially horizontal portion above said lining and innersole to the edge thereof, and down along said edge therearound, said upper extending inwardly from said edge beneath said innersole and being cemented thereto, said outersole, innersole, lining, and upper being joined by stitching passing from the upper surface of said horizontal portion of said upper downwardly through said lining, said innersole, and said outersole therebeneath.
